There's a link I remember grabbing a few months ago however I seem to have lost in the process of taking a break from learning Lisp.

Essentially it was a "beautiful"(quote from where I found the link) PDF/HTML document that used some Lisp program to compile all the functions(from the lisp hyperspec) into one flat document that had brief descriptions for all the standard functions(Syntax and very brief descriptions). It also only had information that was useful for programmers(rather than compiler writers), sorted the functions by use(all math, all list functions, and similar), and had a index.
